On Android, from FDroid you can install an app called Seal
I like ytdlnis more.
Lawnchair 2 is no longer under development. The development team always starts to develop a new launcher based on the latest stock launcher every time a new Android version is released (so basically every year). This way the app usually never gets past the alpha or beta builds till they already move on to start from scratch. I don't understand their strategy.
I use Google Lens and I also have to keep Google app installed. I agree it's annoying that they just can't make the apps work standalone. There already is a package that nearly all Google apps dependend on. The package is Google Play Services. Why can't they implement this into Google Play Services as they do with all the other stuff (quick share, find my phone, location services etc...)?
To anyone with a TV running Android I recommend SmartTubeNext: https://github.com/yuliskov/smarttube
I am not aware of any.
Well the messages app that comes with samsung does support Google's RCS as far as I know.
Google implementation of RCS (Jibe I think it's called) is proprietary. A third party client has to be explicitly allowed and supported by Google.
Did you flash a custom ROM? Maybe it will work with a custom ROM.
EDIT: Your phone uses Mediatek processor, so it's not going to be well supported. I recommend you to stick to locked bootloader and just live with the phone as it is.
It works perfectly on my phone (Poco X3 NFC). It is probably different from phone to phone.
